NICHOLAS CHARLES SZERELMEY, OF BELGBAVE ROAD, PIMLICO, ASSIGNOR TO WlL- LIAM HENRY VALPY, OF NO. 8 ORAIGS COUR T, OHARING GROSS, ENGLAND.

Letters Patent No. 92,225, dated July 6, 1869; patented in England, January 29, 1869.

The Schedule referred to in these Letters Patent and making part of the same.

To all to whom it may concern.-

Be it known that I, NrcHoLAs CHARLES Szunut MEY, of Belgrave Road, Pimlico, in the county of Middlesex, England, gentleman, a subject of the Queen of Great Britain, have invented or discovered new and useful Improvements inMaking Tarpaulin in differ- 'ent colors, and in treating sail-cloth and other fabrics, to preserve them from rapid destruction by the seaair and other cori-odiuginfluences; and I, the said NICHOLAS CHARLES SZERELMEY, do hereby declare. the nature of the said invention, and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement thereof; that is to say- This invention has for its object improvements in making tarpaulin in different colors, and in treating sail-cloth and other fabrics, to preserve them from rapid destruction by the sea-air and other corroding influences.

into a mixing-vat or vessel, and the whole is thorough- 1y stirred together. I

\Vhen'the mixing has been continued for about ten minutes, two dances of commercial sulphuric acid are added, and the mixing is continued.

This is compound No. 1, and it is suitable for the I preparation of dark-coloredtarpaulins, and for proserving sail-cloth and other fabrics.

The cloth to be prepared is spread on the ground, and composition, which is heated sufiiciently to render it perfectly fluid, is brushed into it with a hard brush, and so the fabric is thoroughly saturated with the composition. When one side of the fabric has been covered, it is turned over, and the other side is similarly treated. e

For tarpaulins, I frequently apply more than one coating on each side. 4 a

To make a composition suitable for preparing red tarpaulins, I take twenty-eight pounds of rel oxideof iron, and grind it, in a color-mill, with six gallons of Stockholm tar-spirit, and one gallon of rosin-oil, in which two pounds of rosin-powder are dissolved.

After the whole isground, I mix in it six pints of No. 1 compound.

This is compound No.2. I use it in the same manner as the composition No. 1, for tarpuulins, sailcloth, and other fabrics.

Other colors may be prepared in a similar manner, by substituting other pigments for the oxide of .iron.

What I claim, is-

The improvements in making tarpaulins, and in treating sail-cloth and. other fabrics, substantially as above described.
